示例：
Ruby代码

context "a new user" do 
setup { User.new } 
asserts("that it is not yet created") { topic.new_record? } 
end 

context "a new user" do 
setup { User.new } 
asserts("that it is not yet created") { topic.new_record? } 
end 

Javascript代码

Riot.run(function() { 
context('basic riot functionality', function() { 
given('some simple equality tests', function() { 
asserts('a simple truth test should return true', true).isTrue(); 
asserts('isNull is null', null).isNull(); 
}); 

given('another context', function() { 
asserts('equals should compare strings as expected', 'test string').equals('test string'); 
}); 

given('a context concerned with functions', function() { 
asserts('asserts() should allow functions to be compared', function() { 
return 'test string'; 
}).equals('test string'); 
}); 
}); 

given('yet another context', function() { 
asserts('equals should compare strings as expected', 'test string').equals('test string'); 
}); 
});
